TIE-PLATE.

To. all whom it may concern Be it known that I, CLAYFoR T..G RIMM, a citizenof the United States, residlng at Adrian, in the county of Upshur and State drawings, forming partof this specification.

This invention relates to a means com- 'monly"known as a tie plate for holding in proper position the rails ofa more or less temporary track and has'particular application to tie plates for use in mines.

The obj ects of the present invention are first, to provide a perfectly satisfactory tie plate; second, toprovide a tie plate that can be manufactured fora less sum than any other tie plate on the market; and' third, to provide a tie plate which will not shift position but will afford a firm purchase into the pavement, the latter term being used to denote thesolid hard ground in the mine on which the track is laid. There are a number of tie plates on the, market and at least three of these are in quite general use and give a fair measure of satisfaction, but each has its own" inherent defect, for example, one of the'most satisfactory tie rods on'the market gives service in every way except that whenfthemule pullingtlie car kicks against the tie, the kick will shift the tie with respect to the rails. This happens with aggravating frequency and the present invention was ori inated in order toovercome this feature. nother popular tie rod in mine us'e'is objectionable in that while the tie is fairly serviceable, it is practically impossible to disassemble the device within a reasonable-time when it is desired to shift the track to a'difi'er'ent' location. The present invention was made with the thought in mind that removability is an essential ele ment and must be provided for. Still another popular tie rod in mine use is not only very expensive, but after some length of "service tends to open up at the extreme ends which necessitates the taking of the rod to the blacksmith shop for repairs at altogether too frequent'intervals. The stress and opening up of the ends is avoided in the tie plate described herein in that the entire bottom of the parts in cross section.

the plate, except for thehprong on each clamp, is flush with the pavement.

Fig. 5is a plan view thereof. Fig. 6 is a plan view of a modified form of clamp. e

Fig; 7 is a side elevation of such modificat n. I i

My tie 10 is formed of channel iron having the usual flanges'll and 12 and'being turned up at either end as at 14 to form a recess at 18 or square" as shown at 19 andis further provided between such hole and the regcess 15 with an orifice 20 preferably arch. shape as shown in the various figures, but which mayof cour'se'be oblong or'any other shape desired, the purpose'of this orifice being to receive the jaw 21 of the clamp 22.

In "all of the modifications shown the clamp 22 is an integral piece consisting of the body, jaw, and the prong, and inmost of the modifications "6., all except the one Qshown'a't' the left of Fig. 2, alsoh'a'ving an integral lug for holding'the clamp in proper 7 position on the tie. 'In' the preferred form the jaw 21 is fashioned so as to ride over the inner flange 23 of the rail 17 and having a vertical face 24: adapted to abutthe web of such rail, such jaw 21 being approximately the size of the orifice 20 and may if desired be nearly aslarge in cross sectional area as the body of the clamp itself, or it may be merely stamped from a relatively heavy sheet of metal in which case the thickness of the abutting face 24 would be the same as the thickness of the body 22, that is, the

depth of the channel flanges. The prong 25 is best seen in Fig. 2 and consists of a pointed end of the flange bentat right angles and adapted to be firmly pressed into the mine pavement to hold the device in place.

The lug 26 is perforated to receive a holding means which may be a cotter pin 27 having an eye sufiiciently large to receive the point of a pick,- or the fastening means i may consist of a Wedge 28 adapted to be driven in as far as it will go andthen secured in place by a slight tap on the pointed end which will bend the wedge as shown at 29 effectively preventing it from coming loose. The lug 26 is an integral part of the clamp and may be either drawn up from the metal or it may be a separate piece welded thereto, but it is preferablystruckup from the metal as clearly shown in F igshl and 5, the principal advantage of this being cheapness in manufacture.

In Fig.2 on the left hand side I have shown the clamp and tie plate each provided with a circular hole to permit the use of an ordinary bolt which it is intended to apply in the usual way, that is, with the head down and the nut, indicated in dotted lines, on the upper surface for convenience in operation. I do not intend to use a nut and bolt in securing myclamps to the tie plates but have restricted portion 30, and may if desired have two small prongs 3l'shown in dotted lines to aid in holding the tie in place. The real modification, however,of the clamp as shown in these figures consists in slitting the 7 body 22 'as shown at 33 and 34 thus pro viding. two prongs 35' and between them a lug 36 perforated as at 37 to receive the cotter pin or wedge. This modification differs from the preferred form in that there are two prongs and that these prongs are nearer to the rail than is the lug 36 which is just the reverse of the case in the preferred form. It is necessary that the prongs and lugs shall 'not be in vertical alinement in order to l facilitate the driving of the prong or prongs ,It is believed that the operation is now clear. 7 The tie plates are laid loosely on the groundin proper position and therails are then driven firmly into the recesses'15. The clamp 22 is now put in place by lifting the rails and ties and by pushing the jaw 21 up through the orifice 20 and then bringing the lug 26 through the hole 19 which is sufliciently large to permit the arc movement. The cotter or wedge is now driven through the perforation in the lug which holds the clamp in position on the channel bar with the lower surface of the body of the clamp flush with thelower margin. of the channel bar flanges. Now all that remains to do. is to drive the prongs into the pavement which act is performed with any convenient and suitable tool, usually with a pick, but a hammer or sledge should be used if'at hand.
